To all 'whom tm/ty con/cern.-

Be it known that l, GEORGE H. BEsT, a subject of Great Britain, residingat Hampton, in the county of Kings and Province of New Brunswick,Canada, have invented new and useful Improvements inl Set-Rings, .ofwhich the following is a specification.

This invention relates to improvements in set-rings or -collars,f andthe objects of the improvements are to provide for the placing of aset-ring upon any shaft,'for the purpose of taking up end play, or forany other purpose, withoutremoving the shaft or either end of it fromits bearings. j

A further object is to provide a set-ring which may be rmly affixed toashaft without the useof set-screws or bolts or similar` appliances, therin@r when attached having a rimV entirely free from projectingset-screw heads or other projections, thus avoiding the danger toworkmen consequent upon the liability of their clothing to catch upon orbecome entangled by such projections. i

'Fliese objects-are obtained by the mechanisn; illustrated in theaccompanying drawings, in which y Figure 1 is an internal side view ofone.- half or art of one of the sections of the setring. ig. 2 is anexternal side view of the other half of said section. spective view ofboth halves or parts assembled. Fig. 'Li is a vertical section thereof.Fig. 5 is an external side view of one-half or part of the other sectionofthe set-ring. Fig. 6 is an internal side view of the other half ofsaid section. Fig. 7 is a view in perspective of the halves of saidsection partly assembled showing the manner in which they are jointed orfastened together. Fig. 8 is a vertical section thereof. Fig. 9 is aside view of a shaft with both sections of the set-ring thereon andpartly screwed together. Fig. 10 is a similar view showing the set-ringsections completely screwed together and in final position on the shaft.Fig. 11 is a section on Referring s eciflcally to the drawing, theset-ring or col ar is in two sections indicated at 15 and16respectively. The section 15 has an opening 17 for the shaft 18, andon one ide a threads also extends. The sleeve screws into a tapernig andthreaded bore 26 in the section 16.

Fig. 3 is a perrejecting externally-tapering and. ci) sleeve 19 throughwhich the shaft Both sections are split or halved so that they can beplaced on the shaft without removing the latter from its bearings. Thetwo'halves of the section 15 are indicated at 21 and 22, respectively,and on one side thereof are grooves or' channels'23, which when thehalves are placed together, form an annular groove-or channel. thesection 16 are indicated at 24 and 25, respectively, and on one sidethereof are shoulders 26, which when said halves are placed together,form an annular shoulder. Vhen the sections 15 and 16 are assembled onthe yshaft the shoulders 26 enter the grooves 23.

The 'sleeve 19 is rendered reiiexible by making longitudinal saw cuts or'kerfs 27 therein so that when said sleeve is screwed into the bore`20it will be forced against the shaft totightly grip the same.

The parts 24 and 25 are fastened together' by a dovetail joint, theybeing lprovided at their meeting ends with dovetail tenons 28 andmortises 29, the tenon of one of the parts entering the niortiselin theother part, whereby they will be securely fastened together on theshaft.

' lo place the ring on the shaft, the parts 24 and 25. are placed on theshaft from opposite sides'thereof and slid lengthwise thereon to- Wardeach other and interlocked` by sliding the tenons 28 into the Inortises29. The

parts 21 and 22 are then placed to ether'on.

the shaft fromop'posite sides thereo and the sleeve 19 inserted into thebore 20 and The two halves of screwedtogethenwhereby the ring'will be ysecurely fastened on the shaft. Eachring section has holes 30 for aSpanner or lother suitable tool for screwing the parts together.

l/Vhen the ring is secured to the shaft as herein described, there areno screw-heads or other projections extending beyond the periphery. ofthe ring. The ring, maybe made of any size to fit any sized shaft. 'l

The obj ect in breaking the joint by having `the shoulders26 engage withthe grooves 23 is that insome cases the ring might be securely affixedto the shaft and screwed up as tightly as it would go, and yet the twosections of the ring might not come absolutely together. In such a case'the joint herein described would prevent anything from eet- IOO tingbetween the W0 Se@ as o the ring and said gros@ 5 there being means im'neming becoming enmged on thm-amis of the *UE 'e nutecbions together.seeve,
